Hi Thomas,

Thank’s for the recommendation. However, I bumped into some clossloader issue when I tried it on my EAP 6.4+ Keycloak 1.1.7.Final environment.

I keep get the class not found error against RestEasy Client, "java.lang.NoClassDefFoundError: org/jboss/resteasy/client/jaxrs/ResteasyClientBuilder”. Although I’d setup my jboss-deployment-structure.xml in my project under /WEB-INF/. The setting is like below:

<jboss-deployment-structure>

    <deployment>

        <dependencies>

            <module name="org.jboss.resteasy.resteasy-jaxrs" services="import"/>

        </dependencies>

    </deployment>

</jboss-deployment-structure>

Thank you and best regards,

—

Subject: Re: [keycloak-user] How to correctly use REST API? delete user through REST API for example

Hi Jason,

do you really need to use the raw REST API or would it be an option to use the keycloak-admin-client API?

here is an example for creating and deleting a user via the admin-client API:

package de.tdlabs.training.keycloak;

import static java.util.Arrays.asList;

import javax.ws.rs.core.Response;

import org.jboss.resteasy.client.jaxrs.ResteasyClientBuilder;

import org.keycloak.admin.client.Keycloak;

import org.keycloak.admin.client.KeycloakBuilder;

import org.keycloak.representations.idm.CredentialRepresentation;

import org.keycloak.representations.idm.UserRepresentation;

public class KeycloakAdminClientExample {

public static void main(String[] args) throws Exception {

Keycloak kc = KeycloakBuilder.builder() //

.serverUrl("http://localhost:8081/auth") //

.realm("rest-example")//

.username("rest-user-admin") //

.password("password") //

.clientId("admin-cli") //

.resteasyClient(new ResteasyClientBuilder().connectionPoolSize(10).build()) //

.build();

CredentialRepresentation credential = new CredentialRepresentation();

credential.setType(CredentialRepresentation.PASSWORD);

credential.setValue("test123");

credential.setTemporary(false);

UserRepresentation user = new UserRepresentation();

user.setUsername("testuser");

user.setFirstName("Test");

user.setLastName("User");

user.setCredentials(asList(credential));

user.setEnabled(true);

user.setRealmRoles(asList("admin"));

// Create testuser

Response result = kc.realm("rest-example").users().create(user);

if (result.getStatus() != 201) {

System.err.println("Couldn't create user.");

System.exit(0);

}

System.out.println("Testuser created.... verify in keycloak!");

System.out.println("Press any key...");

System.in.read();

// Delete testuser

String locationHeader = result.getHeaderString("Location");

String userId = locationHeader.replaceAll(".*/(.*)$", "$1");

kc.realm("rest-example").users().get(userId).remove();

}

}

Hi there,

Can someone give me some hint about how to correctly setup a client that can accept REST request from a httpclient in keycloak?

For example, I use the admin-access example from keycloak source project and modify it to do a DELETE action through REST API, however I keep getting the request Forbidden 403 from keycloak server. I don’t change any setting of the admin-client imported from the json file and my code snippet of deleting user as below:

public static void deleteUser(HttpServletRequest request, AccessTokenResponse res) throws Failure {

HttpClient client = new DefaultHttpClient();

String userId = "e20277f8-2ebe-4e5e-aa00-0cee9c578249";

try {

HttpDelete delete = new HttpDelete(getBaseUrl(request) + "/admin/realms/demo/users/" + userId);

delete.addHeader("Authorization", "Bearer " + res.getToken());

HttpResponse response = client.execute(delete);

System.out.println(response.getStatusLine().getReasonPhrase());

if (response.getStatusLine().getStatusCode() != 200) {

throw new Failure(response.getStatusLine().getStatusCode());

}

HttpEntity entity = response.getEntity();

InputStream is = entity.getContent();

if (is != null)

is.close();

} catch (IOException e) {

throw new RuntimeException(e);

} finally {

client.getConnectionManager().shutdown();

}

}
